"I bless you, Father, Lord of heaven and of earth, for hiding these things from the learned and the clever and revealing them to little children." (Matthew 11: 25)
God's plan of salvation is filled with mysteries. The learned professors may speculate but the mysteries of the kingdom are revealed to little children like St. Therese of the Little Flower.
"Moses said to God, 'Who am I to go to Pharaoh and bring the Israelites out of Egypt?' 'I shall be with you." (Exodus 3: 11 – 12)
Who am I to do the work of God? - I shall be with you.
If God is with me, then it is accomplished. If God is with me in the Enterprise, then it is accomplished.
And surely God is with me.
"All powerful God, may the gifts we present bring honor to your saints, and free us from sin in mind and body."
The experience of the Church is that in spite of our Baptism and participation in the sacraments, we still struggle with sins in our mind and body. St. Paul experienced the same thing when he cried out for deliverance from this struggle. Only the Holy Spirit entrenched in us can help us overcome in this struggle.
